No amount of dress rehearsals could prepare them for this: their baby boy is here!

Former Dancing with the Stars professionals Edyta Sliwinska and her husband Alec Mazo welcomed a son, Michael Alexander Mazo, on Saturday, Jan. 4, she confirms to PEOPLE.

“We are extremely happy and in love with him. So far it’s been the most amazing experience of my life,” Sliwinska, 32, tells PEOPLE.

“Even though I’ve been told how incredible it is to be a mom, I never imagined I would enjoy so much every minute spent with my little munchkin.”

After Sliwinska and Mazo, 35, competed on the show for 10 and four seasons respectively, she announced her focus would be shifting to starting a family. In October, the couple — who have been together for 13 years — announced they were they were expecting.
